Three blocks are stacked on top of each other inside an
elevator as shown in (Figure 1).
Answer the following questions with reference to the
eight forces defined as follows.
the force of the 3 kg block on the 2 kg
block, $F_{on\ 2\ by\ 3}$,
the force of the 2 kg block on the 3 kg
block, $F_{on\ 3\ by\ 2}$,
the force of the 3 kg block on the 1 kg
block, $F_{on\ 1\ by\ 3}$,
the force of the 1 kg block on the 3 kg
block, $F_{on\ 3\ by\ 1}$,
the force of the 2 kg block on the 1 kg
block, $F_{on\ 1\ by\ 2}$,
the force of the 1 kg block on the 2 kg
block, $F_{on\ 2\ by\ 1}$,
the force of the 1 kg block on the floor,
$F_{on\ floor\ by\ 1}$, and
the force of the floor on the 1 kg block,
$F_{on\ 1\ by\ floor}$.
k the magnitude of the forces.
rank items as equivalent, overlap them.
$F_{on\ floor\ by\ 1}$ $F_{on\ 1\ by\ floor}$ $F_{on\ 1\ by\ 2}$ $F_{on\ 2\ by\ 1}$ $F_{on\ 2\ by\ 3}$ $F_{on\ 3\ by\ 2}$ $F_{on\ 1\ by\ 3}$
